[U-Boot] [PATCH] Use sizeof(gd_t), not sizeof(struct global_data)
by Loïc Minier 03 Jan '11

03 Jan '11

The eNET (x86) build fails with "invalid application of 'sizeof' to incomplete type 'struct global_data'" because x86 doesn't define struct global_data. Change sizeof(struct global_data) to sizeof(gd_t) which is always available.

[U-Boot] [PATCH] common/dlmalloc: support reinit bin for fast reset
by Macpaul Lin 03 Jan '11

03 Jan '11

There are several way to reset the u-boot. Some platform will use watchdog timeout to reset the system. Some platfrom will jump to 0x0 to reload the u-boot. Some platform will jump to CONFIG_SYS_TEXT_BASE to do fast reset. This patch fixed the problem of static varible didn't cleared on the platforms which "CONFIG_SKIP_LOWLEVEL_INIT" is enabled and do software reset by simply jump to the address "CONFIG_SYS_TEXT_BASE". This patch also introduce a new define named "CONFIG_FAST_RESET" for developer to distinguish this method from other reset methods.

I did something like: a) start fresh: git clean -x -d b) configure with or without objdir make CROSS_COMPILE=arm-linux-gnueabi- O=$PWD/obj omap3_beagle_config c) build (with or without objdir) d) distclean (with or without objdir) and tested combinations like a-d-d, a-b-d-d, a-b-c-d-d, then checked whether any file remained with git clean -x -d -n -- Loïc Minier
